HARRY E. ESSIG, OF'CANTON, OHIO, ASSIGNOR TO THE ESSIG .PIVOT WINDOW COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPORA- WINDOW.

SPECIFICATION forming part of Letters Patent No. 756,006, dated March 29, 190,4. v Application filed November 19, 1908. f Serial No. 181,767. (No model.)

\T all whom it may concern,.-

Be it known that I, HARRY E. Essie, a citizen of the United States, and a resident of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Windows, of which the following is a specification.V 4

My invention relates to windows in which the sash is verticallypivoted in the frame and also has a vertical movement therein, so` that it can swing free of the sill; and the objects of the improvements areto provide a sensitive and eiicient mechanism for lifting the sash to free the sill for sustaining the sashl in its elevated position and for locking it in its various positions of rotation and also to provide a freely-operating top strip which will completely close the varying interval between the top of the sash and the windowframe. I attain these objects by the construction,mechanism, and arrangement illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a Window, showing the sash closed and lowered, with the top strip and adjoining parts in section; Fig. 2, a

perspective view of a window, showing the sash raised and swung open; Fig. 3, a longitudinal section of the sash-lift; Fig. 4,- a crosssection of the same on line 4 4, Fig. 3; Fig. 5, a perspective view of the same with its parts separated, with the face-plates broken away to show the details; Fig. 6, an elevation, partly in section, of the top strip and adjoining parts as located when the sash is closed and lowered; Fig. 7, a view of the same parts as located when the sash is lifted; Fig. 8, an un'der perspective view of part of the upper frame-bar; Fig. 9, a'perspective view of part of the upper sash-bar and the sash-stripwith the fillingsstrips; Fig. 10, a cross-section on line 10 10 of Figs. 1 and 6; Fig. l1, a Vcrosssection on line 11 11 of Fig. 7; Fig. 12, a front view of part of the sash face-plate, and Fig. V13 a rear view of the same.

f Similar numerals refer to similar parts throughout the drawings. p

The window-sash l normally rests on and is pivoted on the sill-strip 2, which preferably projects above the sill proper, 3, and the sash is also pivoted to the sash-strip 4, `which has a free vertical movement in the upper groove 5 in the window-frame 6. The upper and lower edges of the sash are beaded and grooved, as at 7 and 8, and normally engage with the corresponding grooved and beaded faces 9and 10 of the sash-strip and the sillstrip. The sash-strip is normally heldin'engagement with the upper edge of the sash by the coil-spring 11 around the upper pivot 12; but when the sash is turned on its pivots the strip is forced upward by the inclined sides of the beads and grooves to free the one from the other. These parts are ordinary in windows of this class and can be varied in many ways without affecting the nature of this in- Vention.

rlhe sill-plate 13 is formed on or attached in' a suitable mortise in the sill-strip and is provided With the longitudinal socket 14, having the inclined bottom 15, and with the guide-l posts 16, of which there is preferably one at each end. The bearing '17 is formed in one' side of the sill-plate, in which bearing is journaled the short shaft 18, on the outer end ofL which shaft is formed or attached the operating-arm 19. On the inner end of the shaft is formed or mounted the cog-pinion 20, which pinion is preferably located partly in the re'- cess 21 at one side in the bottom of the longitudinal socket. The entire periphery of the pinion can be provided with cogs; but I prefer to omit them on the section of the circumferencenot brought into use, as illustrated.

The wedge-block 22 is located in the inclined socket in the sill-plate, and the inclined'runner 23 is formed on one side of `the block, which runner bears and slides on the inclined bottom ofthe socket alongside of the pinion and its recess, and on the other'side l of the block is formed the inclined rack 24, which rack meshes with the cogs of the pinion. The top of the block is formed horizontal, and in it I prefer'to provide the recess 25, in which recess are located the round pins 26 to form a roller-bearing.

The intermediate plate 27 normally rests on SOl the sill-plate, and on the top or roller-bearing of the wedge-block and in each end are provided the apertures 28, which apertures are of a size to neatly receive the guide-posts, by means of which the intermediate plate is /free to move up and down, but is prevented from any lateral or rotary movement. The lower pivot-post 29 is formed in the middle of the intermediate plate, and the ends 30 of the plate are preferably formed curved concentric with the pivot-post. In the lower side of the' intermediate plate is preferably formed the longitudinal channel 31, in which the rollerbearing operates, and along one side is also formed the groove 32, which receives the similar bead 33 on the sill-plate and forms atight joint against air-currents.

rIhe sash-plate 34 is formed on or attached in a suitable mortise in the lower edge of the sash and is provided with the central bearing 35 for the pivot-post. The depending flanges 36 are preferably provided on the ends of the sash-plates, which flanges are curved to conform to the ends of the intermediate plate, which arrangement brings the lower side of the intermediate plate and the contiguous ends of the sash-plate flush with thelower edge of the sash. In the ends of the sash-plate are provided the apertures or sockets 37, which sockets register with the intermediate-plate apertures and receive the guide-posts of the sill-plates when the sash is closed and lowered, whereby the sash is locked against rotation.

When the sash is in its normal closed and lowered position, the parts of thelifting mech anism are in the position shown in Figs. 1 and 3, with the wedge-block down in the bottom of the inclined socket, and the rack at the thin end of the wedge-block is engaged with the cog-pinion. To lift the sash, the pinion is rotated by the operating-arm, and the block is carried endwise and upward by the inclined rack on the pinion and bythe inclined runner on the bottom of the inclined socket, which movement of the block lifts the intermediate plate and the superimposed sash, so that the beads and grooves on its lower edge are disengaged from those of the sill-strip and the sash-plate sockets are disengaged from the guide-posts of the sill-plate, and the sash is thus free to rotate on its pivots. To sustain the sash in its raised position, the stay-lug 38 is formed on the sill-plate, to pass which lug the operatingarm, which is made of elastic material for the purpose, is required to be bent or sprung slightly outward, so that when the arm is rotated to raise the sash and is forced past the stay-lug, as shown in Figs. 2 and 5, the lug acts to prevent a return rotation, and thereby the sash is sustained until the arm is forced past the lug by the operator, and to lock the sash at various positions in its rotation the latch 39 is pivoted on the sash-plate, which latch is adapted to be operated in and out of the apertures 40, located in the intermediate plate around the pivot-post. The finishing or face plate 4l is preferably provided on the sash to cover the exposed edge. of the sash-plate, on the inner side of which face-plate is pivoted the latch-lever 42, which lever is provided with the inwardly-projecting eccentric-pin 43, adapted to operate in the inclined groove 44 in the side of the latch and also with the outwardly-projecting pin 45,adapted to operate in the curved slot 46 in the face-plate, on the outer end of which latter pin is preferably provided the knob 47, by means of which lever the latch is operated. By rotating the lever toward the latch-pivot 39 the lever-pin operating in the latch-groove throws the bolt upward to clear the intermediate-plate apertures, and by rotating the lever away from the latch-pivot the bolt is thrown down to enter in one of these apertures, thereby stopping the window against rotation.

The dovetail grooves or channels 48 are provided in the upper side of the sash-strip and extend from the pivot-plate 49 each way to the ends of the strip. The wedge-shape tilling strips 50 are located in the dovetail grooves, and the bow-springs 51, which are attached in the grooves 52 in the under sides of the wedge-strips` act against the bottoms of the dovetail channels in the sash-strip to force the Wedge-strips upward against the window-frame and when the sash is closed to force the ends of the sash-strip down against the upper edge of the sash. These parts are so arranged and proportioned that when the sash is lowered the inclined sides of the wedgestrips close up against the inclined sides of the dovetail grooves, thereby making a completely tight joint between the sash and the frame, as shown in Figs. 6 and 10. The sides of these strips and grooves can be formed vertical with fairly good results; but I prefer to incline them as illustrated and described, because a tighter fit of the strips in the grooves can thereby be made when the sash is lowered without any binding of the strip on the groove when the sash is being raised.

The free plates 53 are vertically located on one or both sides of the pivot-plate and extend the entire space between the inner ends of the wedge-strips. rIhese plates operate freely up and down in the similar sockets 54 in the frame. The free plates serve to completely close the interval between the inner ends of the wedge-strips and merely rest on the top of the sash-strip and conform to its movements up and down. The guide-pins 55 are provided in the upper frame-groove near the sides of the window and extend down through the apertures 56 in the wedge-strips. pins enter the apertures 57 in the sash-Strip when the sash is raised, thereby stiffening and steadying these parts together and retaining the wedge-strips in proper endwise position, and the guide-pins 58 are provided in the upper frame-groove near the middle of the These.
